Re-Center text position as str length changes

I am new to javascript and am having an issue repositioning animated text as the string length varies. I have an SVG element and a string within it, where that string needs to be centered within that SVG. Using ' | ' as a center reference, the centering would look like:
| | |
g g g g g g
If I start the animation with a str of len 3, it will be centered properly for Len 3 strs, but then other lens would be equivalent to:
| |
g g g
Example code:
function animateValue(obj, start, end, duration) {
let startTimestamp = null;
const step = (timestamp) => {
if (!startTimestamp) startTimestamp = timestamp;
const progress = Math.min((timestamp - startTimestamp) / duration, 1);
const str = obj.innerHTML;
// console.log(`${str.length}` );
if (`${str.length}`==="1"){
obj.style.x = '200px';
}
obj.innerHTML = Math.floor(progress * (end - start) + start);
if (progress < 1) {
window.requestAnimationFrame(step);
}
};
window.requestAnimationFrame(step);
}
const obj = document.getElementById("heading");
animateValue(obj, 100, 0, 5000);
svg {
position: absolute ;
width: 40%;
border: 1px solid rgba(255,255,255,0.3);
margin-left: 30%;
border-radius: 50%;
}

I have tried re-arranging the divs to allow for the absolute and relative positioning, however that was not properly maintaining size relationships as needed.

If you use dominant-baseline="middle" text-anchor="middle" on the text element and position it in the middle of the SVG (250,250) it should work.
function animateValue(obj, start, end, duration) {
let startTimestamp = null;
const step = (timestamp) => {
if (!startTimestamp) startTimestamp = timestamp;
const progress = Math.min((timestamp - startTimestamp) / duration, 1);
obj.innerHTML = Math.floor(progress * (end - start) + start);
if (progress < 1) {
window.requestAnimationFrame(step);
}
};
window.requestAnimationFrame(step);
}
const obj = document.getElementById("heading");
animateValue(obj, 200, 0, 5000);

Isolate section of SVG when mouse is hovered

I am attempting to build an interactive map from scratch. I have an SVG of the map of Canada that has separate layers for each province. I'd like to highlight a specific province/territory when the mouse is hovered over it.
I have tried using a function that gets the live update of the mouse coordinates, but I am unsure as to how to figure out which section of the image it is on. I am unsure as to if this is the best method of doing it.
Through some of my research, I have found a method of gathering the pointer coordinates:
let x = 0;
let y = 0;
function showCoords() {
x = event.clientX;
y = event.clientY;
}
And I call it around the SVG using:
<div onmousemove="showCoords()">
...SVG HERE
</div>
I can select the different layers inside of the SVG, but the question is if I can find a way of checking which layer my mouse is currently over.
Thank you!
Edit:
I have reached a solution that accomplishes my goal, but I am unsure as to if it is efficient.
Using CSS, I fill each group upon hover:
#canada {
fill: hsl(0, 0%, 29%);
}
#canada g {
transition: .3s;
}
#canada g:hover {
fill: hsl(189, 88%, 59%);
}
I am also using the onClick option on each group to pull up their dialogue.

Maybe something like this? Just keep "data-name" attribute on each <g> inside svg code.
let x = 0;
let y = 0;
let svgCountry = document.querySelector("#states svg");
let svgStates = svgCountry.querySelectorAll("[data-name]");
let resContainer = document.getElementById("state-hovered-is");
// init tooltip
function showCoords(event) {
let x = event.clientX;
let y = event.clientY;
resContainer.setAttribute("style", "left:" + (x + 15) + "px;" + "top:" + (y - 50) + "px;");
}
// close tooltip
function clearCoor() {
resContainer.innerHTML = "";
}
// clear everything
function clearAllOn() {
svgStates.forEach(function(el) {
el.classList.remove("hover");
resContainer.innerHTML = "";
console.clear();
});
}
// display current state in div
function displayState(el) {
var res = el.getAttribute("data-name");
el.classList.add("hover");
resContainer.innerHTML = "<p>You're at" + " " + res + "</p>";
console.log(res);
}
svgStates.forEach(function(el) {
// mouse events
el.addEventListener("mouseenter", function() {
displayState(el);
});
el.addEventListener("mouseleave", function() {
clearAllOn();
});
// touch events
el.addEventListener("touchstart", function() {
clearAllOn();
displayState(el);
});
});

Javscript to dynamically build HTML/SVG for mobile view

I have a full screen SVG image/mask reveal; it works great on desktop but it doesn't scale/fit on mobile devices. So im guessing the best solution would be to dynamically build the SVG and SVG container depending on screen width and have a mobile & desktop build. So i'm looking for advice and the best solution and if someone could point me in the right direction or know of an example I can look at.
// DRAW SVG MASK /////////////////////////////
var svg = document.querySelector("#svg__bg");
var tl = new gsap.timeline({ onUpdate: onUpdate });
var pt = svg.createSVGPoint();
var ratio = 0.5625;
tl.to("#masker", {duration: 2, attr: {r: 2400}, ease: "power2.in" });
tl.reversed(true);
function mouseHandler() {
tl.reversed(!tl.reversed());
}
function getPoint(evt) {
pt.x = evt.clientX;
pt.y = evt.clientY;
return pt.matrixTransform(svg.getScreenCTM().inverse());
}
function mouseMove(evt) {
var newPoint = getPoint(evt);
gsap.set("#dot", { cx: newPoint.x, cy: newPoint.y });
gsap.to("#ring, #masker", {duration: 0.88, attr: { cx: newPoint.x, cy: newPoint.y }, ease: "power2.out" });
}
function onUpdate() {
var prog = (tl.progress() * 100);
}
function newSize() {
var w = window.innerWidth;
var h = window.innerHeight;
if (w > h * (16 / 9)) {
gsap.set("#svg__bg", { attr: { width: w, height: w * ratio } });
} else {
gsap.set("#svg__bg", {
attr: {
width: h / ratio,
height: h
}
});
}
var data = svg.getBoundingClientRect();
gsap.set("#svg__bg", {
x: w / 2 - data.width / 2
});
gsap.set("#svg__bg", {
y: h / 2 - data.height / 2
});
}

window.addEventListener("mouseup", mouseHandler);
window.addEventListener("mousemove", mouseMove);

svg to canvas image in jspdf - I Get a black content

I've used jspdf to convert the svg image to canvas and then to pdf
The plugins I've used are

I'm unable to get the exact image that is required as an output when I generate it to pdf.
I'm converting the svg to canvas but still I'm unable to get the desired output. Instead of the exact image I get a black content inside that.
The css code for the above one is
.bullet {
font: 10 px sans-serif;
}
.bullet.marker {
stroke: #000;
stroke-width: 2px;
}
.bullet .tick line {
stroke: # 666;
stroke-width: .5px;
}
.bullet.range.s0 {
fill: #eee;
}
.bullet.range.s1 {
fill: #ddd;
}
.bullet.range.s2 {
fill: #ccc;
}
.bullet.measure.s0 {
fill: steelblue;
}
.bullet.measure.s1 {
fill: #fff;
}
.bullet.measure.s2 {
fill: steelblue;
}
.bullet.measure.s3 {
fill: lightsteelblue;
}
.bullet.title {
font-size: 10px;
font-weight: bold;
}
.bullet.subtitle {
fill: #999;
}
The javascript that helps me rendering the data is
function genPdf(){
var svgElements = $("#page-content-wrapper").find('svg');
//replace all svgs with a temp canvas
svgElements.each(function() {
var canvas, xml;
canvas = document.createElement("canvas");
canvas.className = "screenShotTempCanvas";
// canvas.getContext("3d");
//convert SVG into a XML string
xml = (new XMLSerializer()).serializeToString(this);
// Removing the name space as IE throws an error
xml = xml.replace(/xmlns=\"http:\/\/www\.w3\.org\/2000\/svg\"/, '');
//draw the SVG onto a canvas
canvg(canvas, xml);
$(canvas).insertAfter(this);
$(this).addClass('tempHide');
$(this).hide();
});
html2canvas(document.getElementById('page-content-wrapper'), {
onrendered: function (canvas){
var img = canvas.toDataURL("image/jpeg",1.0);
var doc = new jsPDF();
doc.addImage(img, 'JPEG' , 10, 10);
doc.save('test.pdf');
}
});
setTimeout(function(){
$("#page-content-wrapper").find('.screenShotTempCanvas').remove();
$("#page-content-wrapper").find('.tempHide').show().removeClass('tempHide');
$("#page-content-wrapper").find('.bullet').show();
},2000);
}
function getStyle(el, styleProp) {
var camelize = function(str) {
return str.replace(/\-(\w)/g, function(str, letter) {
return letter.toUpperCase();
});
};
if (el.currentStyle) {
return el.currentStyle[camelize(styleProp)];
} else if (document.defaultView && document.defaultView.getComputedStyle) {
return document.defaultView.getComputedStyle(el, null)
.getPropertyValue(styleProp);
} else {
return el.style[camelize(styleProp)];
}
}
Please help me out in this. Thanks

Save result from html2canvas library

I used html2canvas library to get screenshot of the html content using jvascript. That is what html2canvas library does.
What I tried to do is to get a screenshot of the output from html2canvas library and save it in any image format(say jpeg).
But was not able to achieve it.
Here is what I've tried so far:
HTML
<svg width="500" height="350">
<circle id="orange-circle" r="30" cx="50" cy="50" fill="orange" />
<rect id="blue-rectangle" width="50" height="50" x="25" y="200" fill="#0099cc"></rect>
<animate
xlink:href="#orange-circle"
attributeName="cx"
from="50"
to="450"
dur="5s"
begin="0s"
repeatCount="2"
fill="freeze"
id="circ-anim"/>
<animate
xlink:href="#blue-rectangle"
attributeName="x"
from="50"
to="425"
dur="5s"
begin="0s"
repeatCount="indefinite"
fill="freeze"
id="rect-anim"/>
</svg>
CSS
svg {
border: 3px solid #eee;
display: block;
margin: 1em auto;
}
p {
color: #aaa;
text-align: center;
margin: 2em 0;
}
JS(with html2canvas lib)
<script type="text/javascript" src="html2canvas.js"></script>
<script type="text/javascript">
html2canvas(document.body).then(function(canvas) {
document.body.appendChild(canvas);
});
</script>

The only thing you need to do is wrapping the function by a window.onload
Here are the example
window.onload = function() {
$("#convert").click(function(){
html2canvas($('.svgElement')).then(function(canvas) {
var imgLink = canvas.toDataURL("image/png");
var img = document.createElement('img');
img.src = imgLink;
document.body.appendChild(img);
});
});
}
https://jsfiddle.net/t1fw7pgy/1/
In your code, the function is called before render the element, therefore it will just give you a blank canvas page.
